Basic knowledge of RF coaxial cable connectors

RF coaxial cable connectors are functional components that connect, disconnect or switch circuits with the help of electrical signals or mechanical forces. RF coaxial cable connectors transmit electrical signals or electronic energy. Therefore, connectors can be found wherever there are electronic systems. In large electronic systems, tens of thousands of connectors are often required. It can be said that connectors are one of the key components to ensure the normal and safe operation of various electronic systems.

RF coaxial cable connectors

connectors used in RF coaxial feeder systems are generally called RF coaxial connectors. In RF circuits, if you want to maintain a stable predetermined impedance and capacitance, or if you need to shield external electrical interference, you must use coaxial connectors to interconnect. RF coaxial cable connectors are used for RF transmission lines used by communications and electronic equipment to connect RF coaxial cables, or between coaxial and microstrip, coaxial and waveguide. The plug part of the RF coaxial cable connector is often installed at the cable end, and the socket part is often installed on the equipment fixing unit.

 

The connector frequency (wavelength) of RF coaxial cable

divided into meter wave connector, decimeter wave connector, centimeter wave connector and millimeter wave connector. Appearance and structural type: straight connector, bent (usually right angle) connector and T-type connector.

 

The type of connector connection mechanism of RF coaxial cable

threaded connector, bayonet connector, push-in (slide-in) connector, push-in self-locking connector, flange connector and Haff connector, etc.

 

The use status of the connector of RF coaxial cable

free connector and fixed connector. Fixed connectors can be divided into nut mounting connector, thread mounting connector, flange mounting connector and welding mounting connector.

 

The connector termination type of RF coaxial cable

cable connector, coaxial microstrip connector, hard coaxial connector and welding wire connector.

 

The performance of the connector of RF coaxial cable

three types of connectors: 0 level, 1 level and 2 level. The 0 level connector is also called the standard test connector for testing.

 

The connector uses of RF coaxial cable

military connector, civilian connector, general connector, precision connector, high voltage connector, high power connector, adjustable phase connector, radiation-resistant connector, triaxial connector and other special connectors.

 

The connector interface polarity of RF coaxial cable

positive (usually with pin) connector, negative (usually with jack) connector and non-polar (neutral) connector. There will also be positive-positive connector, negative-positive connector and negative-negative connector in the converter.

 

The connector naming method of RF coaxial cable is classified into

SMA, SMB, SMC, SMP, QMA, BMA, MCX, MMCX, F, UHF, 1.0/2.3, 1.6/5.6, BNC, TNC, N, 7/16, etc.
